tests: simplify common setup A few of the tests were missing basic sanity checks, while most of them were doing copy-and-paste initialization (in fact, some of them pasted the argc > 1 check more than once!). It's much nicer to do things in one common place, and minimizes the size of the next patch that fixes getcwd usage. * tests/testutils.h (EXIT_AM_HARDFAIL): New define. (progname, abs_srcdir): Define for all tests. (VIRT_TEST_MAIN): Change callback signature. * tests/testutils.c (virtTestMain): Do more common init. * tests/commandtest.c (mymain): Simplify. * tests/cputest.c (mymain): Likewise. * tests/esxutilstest.c (mymain): Likewise. * tests/eventtest.c (mymain): Likewise. * tests/hashtest.c (mymain): Likewise. * tests/networkxml2xmltest.c (mymain): Likewise. * tests/nodedevxml2xmltest.c (myname): Likewise. * tests/nodeinfotest.c (mymain): Likewise. * tests/nwfilterxml2xmltest.c (mymain): Likewise. * tests/qemuargv2xmltest.c (mymain): Likewise. * tests/qemuhelptest.c (mymain): Likewise. * tests/qemuxml2argvtest.c (mymain): Likewise. * tests/qemuxml2xmltest.c (mymain): Likewise. * tests/qparamtest.c (mymain): Likewise. * tests/sexpr2xmltest.c (mymain): Likewise. * tests/sockettest.c (mymain): Likewise. * tests/statstest.c (mymain): Likewise. * tests/storagepoolxml2xmltest.c (mymain): Likewise. * tests/storagevolxml2xmltest.c (mymain): Likewise. * tests/virbuftest.c (mymain): Likewise. * tests/virshtest.c (mymain): Likewise. * tests/vmx2xmltest.c (mymain): Likewise. * tests/xencapstest.c (mymain): Likewise. * tests/xmconfigtest.c (mymain): Likewise. * tests/xml2sexprtest.c (mymain): Likewise. * tests/xml2vmxtest.c (mymain): Likewise.
